The 'EDC' introduces a new functional style to the William Henry collection. We've always worked with our own hybrid combination of technology and handwork to create unique tools, and on this new model we've incorporated the most modern three-dimensional machining into our frame. The sculpted texture and shape of each frame is machined from solid aircraft grade aluminum alloy, hard-anodized to military specs for a lifetime of superlative performance. Each 'EDC' features a blade of D2 German tool steel, one of the most storied and respected steels in the modern history of cutlery. Tempered to HRC 60-61, this exceptional steel is rugged and durable, capable of achieving and holding an exceptional razor edge. The blades are precision machined and then finished entirely by hand to a beautiful satin luster that is a hallmark of William Henry's blade work. A synthetic diamond-like coating (DLC) is bonded to the blade at a molecular level and tough enough for any application. True to form, we also use the finest organic and high-tech materials as inlays into the aluminum frame - each piece finished by hand to our exacting standards, and providing a warm and elegant counterpoint to the stark precision of the textured handle. The pocket clip and fittings are crafted from stainless steel and titanium, tempered as necessary for optimal wear resistance, and the 'EDC' incorporates our renowned button lock for safe one hand operation open and closed. Each piece features a serial number engraved below the logo on the blade and includes a certificate of authenticity.
